MVC design minus the M - Joomla! Forum - community, help and support

up point i've been doing component development on 2.5 without doing , taking advantage of mvc.

following hello world tutorial (http://docs.joomla.org/developing_a_mod ... troduction) i've created own component pieces need have couple of questions.

right view have: site/views/mycomponent/view.html.php

code: select all

   function display($tpl = null)
   {
      // display view
      parent::display($tpl);
   }

then have site\views\mycomponent\tmpl\default.php has front end code.

my first question view.html.php. code need?

now next problem don't use models @ all. i'm not sure kind of file create , where. plus how used?

for example view default.php: site\views\mycomponent\tmpl\default.php

code: select all

   // dont allow direct linking
   defined('_jexec') or die('direct access location not allowed.');
    // user , session data.
    $user =& jfactory::getuser();
    $db =& jfactory::getdbo();
   $doc =& jfactory::getdocument();
   
   //list cameras - needed active cameras table
   $query_camera_name = "select camera_name, camera_status, camera_quality, email_notice, camera_hash, camera_type, camera_sensitivity, camera_user, camera_pass, camera_ip, camera_port #__cameras user_id=".(int)($user->id)." , camera_status!='deleted'";
   $db->setquery($query_camera_name);
   //get number of cameras - needed active cameras table
   $db->query();
   $num_rows = $db->getnumrows();
   // can use array names loadassoclist.
   $result_cameras = $db->loadassoclist();
   
   //get user(id) hash  - needed active cameras table
   $query = 'select id_hash `#__users`';
   $query  .= ' `user_id` = ' . (int)($user->id);
   $db->setquery($query);
   $id_hash = $db->loadresult();

//then jquery ajax code , html code


from understand should put queries in model. have update queries in controller. tried:

code: select all

// import joomla modelitem library
jimport('joomla.application.component.modelitem');
 
/**
 * helloworld model
 */
class helloworldmodelhelloworld extends jmodelitem
{
        public function getuserid()
        {
                   $query = 'select id_hash `#__users`';
                   $query  .= ' `user_id` = ' . (int)($user->id);
                   $db->setquery($query);
                   return $db->loadresult();
        }
}

this model created here: site/models/mycomponent.php. thought called "getuserid" in view default.php (or add accordingly controller). doesn't seem work. in advance.
